Italian bee
Encyclopedia
Apis mellifera ligustica is the Italian bee which is a sub-species of the western honey bee (Apis mellifera).

Origin

The Italian honey bee is thought to originate from the continental part of Italy

Italian bees, having been conditioned to the warmer climate of the central Mediterranean, are less able to cope with the "hard" winters and cool, wet springs of more northern latitude
Latitude
In geography, the latitude of a location on the Earth is the angular distance of that location south or north of the Equator. The latitude is an angle, and is usually measured in degrees . The equator has a latitude of 0°, the North pole has a latitude of 90° north , and the South pole has a...

Winter cluster
In beekeeping, a winter cluster is a well-defined cluster of honey bees that forms inside a beehive when the air temperature dips below 54 to 57 °F . Honey bees are but a few insects that survive the winter as a hive. As the outside air temperature decreases the winter cluster becomes tighter and...

s. More food has to be consumed to compensate for the greater heat loss from the loose cluster. The tendency to raise brood late in autumn also increases food consumption.

Anatomy

  • Color: Abdomen has brown and yellow bands. Among different strains of Italian bees there are three different colors: Leather; bright yellow (golden); and very pale yellow (Cordovan).
  • Size: The bodies are smaller and their overhairs shorter than those of the darker honeybee races
  • Tongue length: 6.3 to 6.6 mm
  • Mean cubital index
    Cubital index
    Cubital index is the ratio of two of the wing vein segments of honeybees. The cubital index is used in morphology, the study of form and structure, one way to differentiate species and sub species of living organisms. The pattern of the veins of the fore wings is specific for each breed of bees. ...

Disease resistance

There is no clear evidence that ligustica are any more resistant to acarine mites than the Northern dark bee. They also appear to be less tolerant of Nosema

than Northern dark bees. They are unable to retain faeces in the gut for long periods and require more frequent cleaning flights than the dark bees. They are affected by the parasitic varroa mite, Tracheal Mites, and the bacterial diseases European Foulbrood, American Foul Brood, Chalkbrood and other diseases of the honey bee.

Characteristics

It has a reputation for gentleness, but hybrids with the darker races can be especially vicious.

 bee, characterized the Italian bee in his book Breeding the Honeybee:
While the Italian bee has many strong points, among the A.m. Ligustica it has a large number of weak points:

Strong

  • shows strong disposition to breeding and very prolific
  • excellent housekeeper (which some scientists think might be a factor in disease resistance)
  • uses little propolis
  • excellent foragers
  • superb comb builder:- Writing in Switzerland in 1862, H. C. Hermann stated the comb of an Italian bee-cell occupied only 15 cells for every 16 of the common black bee, and the cubic content was larger by 30 per cent.
  • covers the honey

     with brilliant white cappings
  • shows lower swarming tendency than other Western honey bee races
  • for areas with continuous nectar flow and favorable weather throughout the summer
  • industry
  • gentleness
  • fertility
  • reluctance to swarm
  • zeal for building comb
  • white honey-cappings
  • a willingness to enter supers
  • cleanliness
  • tendency to collect flower honey rather than honey dew. (of value only in countries where the colour of the honey determines the price)

Weak

  • lacks vitality
  • inclined to excessive brood rearing
  • susceptibility to disease
  • high consumption of stores
  • more prone to drifting and robbing
    Robbing
    Robbing is a term used in beekeeping. Bees from one beehive will try to rob honey from another hive. Robbing behavior is especially strong when there is little nectar in the field. Strong colonies with the largest stores are the most apt to prey upon weaker colonies. Some robbing is carried out...

     than the other principal races of Europe.
  • often the strong brood rearing disposition and resulting large food consumption in late winter or early spring causes spring dwindling and hence slow or tardy spring development
  • brood rearing starts late and lasts long into late Summer or Autumn, irrespective of nectar flow
  • tends to forage over shorter distances than either carnica or mellifera, and may therefore be less effective in poorer nectar flows.
  • apparently lacks the ability to ripen heather honey before sealing.
  • for cool maritime regions
  • for areas with strong spring flow
  • for areas with periods of dearth of nectar in the summer

Selective breeding

Breeders of Italian bees as well as other honey bee races look for certain beneficial characteristics. Depending on the breeding goal one or more of the following characteristics will be emphasized.
  1. Gentleness or excitability
  2. Resistance to various diseases and the tracheal mite plus the Varroa mite
  3. Early spring buildup in population
  4. Wintering ability
  5. Not prone to excess swarming
  6. Ripens honey rapidly
  7. Honeycomb cappings are white
  8. Minimal use of propolis
  9. Availability and queen cost
  10. Color
